i bought the CISS and works like a charm. i am a event photographer and thinking of using this system for my photobooth. i have been testing it for couple of days and printing hi quality prints on a 4x6 and 8x11 and i barely notice a decrease on the ink usage, color quality is excellent.

i have recommended this product to a lot of my fellow photographers and will definitely test it out.
Installation wasnt a problem, CISINK provides a very dumb proof instructions, the only think i could have gotten with the package is a double adhesive tape or a Velcro for attaching the ink tank on the side of my printer. Thank you CISINK!
